1. Warm-up September 1st
Answer the following questions with your partner on a piece of paper to turn in:
What are the 5 stages to the water cycle?
How do clouds form?
What is the heat source for the water cycle?
Where does water run off to in the water cycle?
What is the process called when trees give off water?

2. Understanding Heat Transfer: Conduction, Convection and Radiation

3. Heat Transfer Heat always moves from a warmer place to a cooler place.
Hot objects in a cooler room will cool to room temperature.
Cold objects in a warmer room will
heat up to room temperature.

4. Heat transfers in three ways: Conduction Convection Radiation
Heat Transfer Methods
Heat transfers in three ways:
Conduction
Convection
Radiation

5. Conduction
The transfer of heat energy from one substance to another through direct contact. Heat transfers from the warmer part of the object to the cooler part of the object

6. Convection
Transfer of heat through the movement of particles. Convection occurs in liquids and gases. This occurs in a circular motion as warm particles rise and cooler particles sink.

7. Where is the freezer compartment put in a fridge?
Convection Heat
Cold air sinks
Where is the freezer compartment put in a fridge?
Freezer compartment
It is warmer at the bottom, so this warmer air rises and a convection current is set up.
It is put at the top, because cool air sinks, so it cools the food on the way down.

8. Radiation
Energy that travels across distances as certain types of waves.
